Rename the installed import root from the generic top-level skills.* namespace
to a single watermark_remover package. The on-disk Claude-skill layout is
unchanged; only package-dir mapping and the console-script targets move.

Add the metadata a PyPI project page needs: readme, urls, keywords. Rewrite
README links to absolute URLs so they resolve off-GitHub, and lead the quick
start with pip install and the wm commands rather than a clone.

Replace the PEP 639-deprecated license table and classifier with an SPDX
license expression plus license-files.

Add release-pypi.yml, publishing via Trusted Publishing on v* tags so no API
token is stored. Correct the stale pythoughts-labs org name to PyModel across
the workflows, compose file, and docs, since Trusted Publishing binds to the
exact current repository owner.
Validate uploaded file paths in the demo: resolve strictly, require the file to
live under the system temp dir, reject symlinks and non-regular files, and
sanitize the stem and suffix used to build the output name.

Pass the tag through a step-level environment variable in the image release
workflow and validate its format before use, so a crafted ref name cannot be
interpolated into the shell.

Re-pin existing upstream checkouts in the MarkLLM and MarkDiffusion setup
scripts: an existing .git directory previously short-circuited fetch, detached
checkout, sparse-checkout, and HEAD verification, so a stale or tampered tree
was installed as-is.

Guard os.fchmod behind a hasattr check. It does not exist on Windows, which was
failing the Windows CI job on any in-place operation.
image_meta.detect_format reports the whole HEIF/HEIC family as "heif"
(via heif_meta.detect_heif) and never returns "heic", but classify_bytes
and classify only matched "heic" — HEIF bytes without a known extension
classified as "unknown" and were refused by the server handlers. Unify
all three sniffers on one _IMAGE_FORMAT_NAMES constant so the lists
cannot drift apart again.
clean_pdf only reached the pypdf path when exiftool was absent. When
exiftool was installed but exited non-zero or raised, it published the
original unstripped bytes under mode "exiftool" with no degraded flag.
Now a failed exiftool hands off to clean_pdf_pypdf (skip_exiftool avoids
re-invoking the same failing command), which reports mode/degraded
honestly and never silently ships marked bytes.

📝 Walkthrough

Walkthrough

The pull request adds PyPI and container release workflows, updates package metadata and repository references, hardens upload and atomic file handling, improves image and PDF processing, and validates pinned backend checkouts.

Changes

Release packaging and repository migration

Layer / File(s) Summary
Python package publication
.github/workflows/release-pypi.yml, .gitignore, pyproject.toml, skills/remove-ai-marks/__init__.py
The package now maps to watermark_remover and publishes validated builds to PyPI with Trusted Publishing.
Container image publication
.github/workflows/release-images.yml, compose.yaml, skills/remove-ai-marks/references/service-mode.md, tests/test_release_hardening.py
Release image tags validate github.ref_name. Image references now use the ghcr.io/pymodel/watermark-remover namespace.
Repository and documentation references
CODE_OF_CONDUCT.md, README.md, SECURITY.md, docs/windows-autostart.md
Repository, security, conduct, clone, badge, and documentation links now target PyModel/watermark-remover.

File handling hardening

Layer / File(s) Summary
Upload validation and output naming
demo.py, tests/test_release_hardening.py
Uploads must be regular files inside the system temporary directory without symlink traversal. Output names are sanitized.
Race-resistant atomic writes
skills/clean-user-facing-text/scripts/common.py, tests/test_release_hardening.py
safe_write_bytes validates path identities around replacement and rejects symlink, aliasing, and parent-directory races.
Portable backup publication
skills/remove-ai-marks/scripts/clean_asset.py, skills/remove-ai-marks/scripts/common.py, tests/test_clean_asset.py, tests/test_clean_text.py, tests/test_image_degrade.py, tests/test_external_command.py
Backup mode handling supports platforms without os.fchmod. Tests cover byte preservation, rollback, permissions, and mocked process completion.

Media processing and checkout correctness

Layer / File(s) Summary
Unified image format detection
skills/remove-ai-marks/scripts/asset_kind.py, tests/test_format_dispatch.py
Image classifiers use a shared format set. HEIF payloads are classified across extension cases.
PDF metadata fallback
skills/remove-ai-marks/scripts/container_meta.py, tests/test_pdf_structural_rewrite.py
PDF cleaning uses pypdf or a degraded original-file copy after exiftool failure and avoids retrying exiftool.
Pinned backend checkout validation
skills/remove-ai-marks/scripts/setup_markdiffusion.sh, skills/remove-ai-marks/scripts/setup_markllm.sh, tests/test_release_hardening.py
Setup scripts validate resolved commit SHAs for cloned and existing checkouts before installation.

Inline comments:
In @.github/workflows/release-pypi.yml:
- Line 23: Update the actions/checkout step to set persist-credentials to false,
ensuring the checkout token is not retained for subsequent build-time Git
commands.

In `@demo.py`:
- Around line 34-70: Ensure the temporary workdir created before validation is
removed on every failure path before returning the error tuple. Update the
exception handling around the existing workdir and cleaning flow to clean up
failed uploads while preserving the workdir and dest for successful results.

In `@skills/clean-user-facing-text/scripts/common.py`:
- Around line 180-218: Update the temporary-file creation in the atomic write
flow to use os.open with parent_fd, O_CREAT, and O_EXCL when parent_fd is
available, while preserving the existing path-based fallback otherwise. Keep the
generated temporary name and descriptor anchored to the same directory for
validate_paths, os.replace, and exception cleanup, including correct mode
handling and descriptor ownership around os.fdopen.

In `@skills/remove-ai-marks/scripts/container_meta.py`:
- Around line 1756-1759: The ExifTool strategy must be considered unsuccessful
when output is truncated: update exiftool_ok in clean_pdf to require a zero
return code and false stdout_truncated and stderr_truncated flags, and append
the corresponding degraded/fallback action for truncation. Update _fake_tools so
its fake result exposes both truncation attributes.

In `@skills/remove-ai-marks/scripts/setup_markdiffusion.sh`:
- Around line 94-100: In skills/remove-ai-marks/scripts/setup_markdiffusion.sh
lines 94-100 and skills/remove-ai-marks/scripts/setup_markllm.sh lines 85-99,
update the existing-checkout setup to resolve EXPECTED_SHA before checkout,
reject dirty working trees unless the directory is explicitly tool-owned, and
check out the resolved SHA rather than the mutable REF. Preserve the subsequent
HEAD verification so installation can only proceed from the pinned commit.

In `@tests/test_release_hardening.py`:
- Around line 104-115: Update the source filename in
test_demo_sanitizes_cleaned_output_name to a Windows-valid name such as “report
bad.txt” while retaining characters that exercise output-name normalization;
leave the test assertions and cleanup behavior unchanged.
- Around line 307-315: Update the environment setup around env to construct PATH
with os.pathsep and prefix fake_bin to the inherited env["PATH"], preserving the
existing path entries so the fake git executable is discoverable on all
platforms.

test_demo_sanitizes_cleaned_output_name creates 'report <bad>.txt',
which Windows forbids, and test_existing_checkout_is_repinned_before_install
drives the POSIX .sh setup scripts (Windows ships .ps1 variants). Both now
skip on os.name == 'nt', matching the existing guard in
test_safe_write_bytes_rejects_parent_directory_race. Fixes the red
windows-latest CI job.

- demo: remove the per-upload workdir on failure paths instead of leaking
  it (success keeps it alive; Gradio serves the cleaned file from there)
- pdf: treat truncated exiftool output as a failed strategy in clean_pdf,
  matching clean_pdf_pypdf's contract, so it also falls back to pypdf
- release-pypi: checkout with persist-credentials: false; the job runs no
  git commands after checkout
